Stocks jumped on Wednesday, driving the Dow back above the psychologically important 10,000 mark, as Federal Reserve Chairman Ben Bernanke's positive comments about the economy and unofficial data on Chinese exports spurred hopes for a global recovery.

In testimony prepared for delivery to the U.S. House of Representatives Budget Committee, Bernanke said the economic recovery appeared to be on solid footing and that while a double-dip recession can never be entirely ruled out, he expects the economy to continue growing.

Bernanke is more positive about the economy than the consensus is, at a time when some people are starting to question whether we could get a double dip, said Carl Birkelbach, chairman of Birkelbach Investment Securities in Chicago.

Chinese exports surged about 50 percent in May from a year earlier, sources told Reuters. The sharp gain would suggest the risk of a Chinese economic downturn is very small. The report, which will be officially released on Thursday, fueled a rise in global markets.

The U.S. economy is becoming more solid compared to the rest of the world, but China is still the most solid in a lot of ways, Birkelbach said. To a certain extent, rising tides there will help lift us here.
